I've eaten burritos

But yeah, I'm not at all worried about Mebane. As a matter of fact, I think he might be quietly having his best year yet. The Jets game is a bit of an anomaly I think (maybe he's just tired and needs the bye). I'm definately not one of those guys to go back and watch every play in the game in super slow mo, but IIRC, NY did a pretty good job of stretching run plays out on one play, then cutting it back on a bit of a counter or a trap the next (same as SF did). That gets the d-linemen moving side to side a bit where they're a little easier to plow out of the way with the double team (and Shon Green is a pretty damn powerful runner in his own right). LB's need to stay home to step up and plug the gaps, but maybe their youthful exuberance got them cheating a little big (like they did against ADP). All in all, it was still a damn fine game by our defense. We held them to 80 yards on the ground, 100 in the air and zero offensive TD's. Looking for fault in a game like this is just looking for reasons to be a big whiney baby.
As for what is expected of a 1-tech defensive tackle, I love this bit from PFF a few years ago.
1-Technique (4-3 NT) – Pat Williams
The 1-technique does much the same as the 0-technique, except he is shaded over the inside shoulder of one of the guards, and is rarely expected to control two gaps. He is, however, expected to command a double team from the center and guard, which frees up other linemen to be one on one with their blockers. Pat Williams has been the prototype for this position for years. Williams was an immovable force in the middle for the Vikings and required two players to try and shift him from the point of attack, leaving Kevin Williams single-blocked by a guard, and allowing linebackers to run free to the ball and make stops close to the line of scrimmage. A good 1-technique DT can dramatically improve an entire run defense, because he makes several players’ jobs much easier.
Alternative prototypes: Haloti Ngata, Antonio Dixon, Colin Cole*
*lol, Colin Cole...
So you're admitting I'm a celeb...
